Specification of Letters Patent.

Patented. April 16, 1907.

Application filed May 1, 1906. Serial No. 314.696.

To all whom it may concern.-

Be it knownthat I, CARL A. SoHLAoHTEn, a citizen of the United States,residingat Rockwell City, in the county of Calhoun and State of Iowa,have invented a new and useful Tire-Armor, cfwhich the following is aspecification.

The present invention relates to a shoe or armor construction adapted tobe used on pneumatic or other tires for self-pro elled vehicles. Itsobject is to providea evice of this character which is of simple andsubstantial construction and positive and eflicient in operation forpreventing skidding and slipping and for increasing the tractive efiect.

To these ends the invention comprises a tire-shoe composed of a'numberofsubstantially semicircular members adapted to extend around the outsideof the tire in with outwardly-extending'ribs that are adapted topenetratethe surface 'ofthe road and to positively prevent the wheelfrom slipping or skidding. These webs or blades are so constructed as tobest perform their function and withstand thqstrain put upon them. l

The inner ends of the members disposed on the same side of the wheel areconnected together by links to which they are riveted, This permits ofample flexibility in the armor and at the same time enables said armorto be securely held on the tire.

For a more complete understanding of the details of construction andarrangement of parts reference is to be had to the followingdescription, taken in connection with the accompanying drawings, whilethe features of novelty are .set forth in the claims appended hereto.

In the accompanying drawings which illustrate one embodiment of theinvention, Figure 1 is a side elevation of a portion .of a

vehicle-wheel, showing the tire-armor attached thereto. Fig. 2 is atransverse section on line 2 2, Fig. 1. Fig. 3 is a perspective view ofa portion of the armor removed. Fi 4 is a detail view of a modified formofl'nk for connecting the ends of the armor.

Fig. 5 is a sectional view taken on the line- 5 5, Fig. 4.

Referring to the-drawings, .1 represents a Vehicle-wheel shod with apneumatic tire 2,

. preventing skidding and slipping. "3 comprises a lurality of'members4, which on which is arranged a shoe or armor 3 for The shoe are'substantia ly s'emicircular, so as to fit around. the outside of thetire in a radial position thereon. Extending outwardly rom the middleportion of each member is a blade or web 5, which is adapted topenetrate the road-surface and'prevent skidding,

of the wheel. These webs are preferably, although not necessarily,formed integral with the members 4, and can be forged or stamped to thedesired configuratibn. They are made of metal of sui'licient thicknessto withstand the strain subjected upon them Fig. 3,--soas to withstandthe strain, and

viewed from in front the root portions of the webs follow the curvatureof the members 4, as shown in Fig. 2, and the outer edges extendtangentially. By this arrangement the ends 7 of the webs are of greaterde th thanthe intermediate ortions, so that t ey penetrate deeper into t1e sand or mud, so as to better prevent slipping or skidding.

The ends of the members are connected by means of two sets of links 8,to which they are pivoted, thus connectin the members to form a singlestructure or c ain, the ends of which are united by means of thumb nutsand screws 9.

It will be noted that the links permit the members to move one withrespect to another, so as to follow the compression of the tire andreturn as the latter expand, so that the shoe does not diminish theelasticity derived from the tire.

It is to be furthermore noted that the peculiar arc-shaped form of theblades besides providing a substantial construction is intendedprimarily to prevent sidewise slipping or skidding of the wheels.

Referring to Figs. 4 and 5, a modified construction of the end connectin1 links is shown. This comprises a pairo links 10, located on each sideof the armor and riveted or pivoted to one end of the chain or armorstructure, as indicated at 11. On the oppo site end of the armorstructure are rivets 12, one on each side, as indicated in Fig. 5. Theserivets, while serving to connect the member 4 with the links 8 adjacentthe end of the armor, also serve to engage the links 10. The links ofeach pair areprovided with inclined slots 13, the slots of one linkextending inwardly in an inclined direction, while tivelv to the wheeland the other by an out-- ward' inovement. By providing the two links,as shown, the degree of safety of the connections is doubled I havedescribed the principle of the operation of the invention together withthe apparatus which I now consider to be the best embodiment thereof;but I desire to have it understood that the apparatus shown is merelyillustrative and that the invention can,'be carried out. by other means.I

What I claim as new,v and desire to secure by Letters Patent, is y 1. Ina shoe for vehicle-tires, the combination of a plurality ofantiskiddingmembers comprising substantially semicircular piecesextendin around the outside of the tire and apertureii at their ends andeach provided with a middle portion wider than the rest and formed witha radially-extending integral web which is arc-shaped in the directionof its length and is straight at the outer edge, two sets of aperturedlinks,-rivets for connecting the apertured endsof the said members'withthe links to form a chain structure, and devices for adjustably con-.

necting the ends of the said structure to gether. I

2. Ashoe for vehicle-tires, comprising a plurality of antiskiddingmembers extending around the out-side of the tire, links'for connectingthe ends of said members to form a chain structure, and means forconnecting the ends of said structure, comprising a plurahty of memberspivoted to each side of the latter and provided withoppositely-extending slots, and devices on the other end of thestructure engaging in the said slots.

3. A shoe for vehicle-tires, comprising a plurality of antiskiddingmembers extending around the outside of the tire, links for connectingthe ends. of said members to form a chain structure, and means forconnect-mg the ends of said structure, comprising a pair of linksarranged on each side of the structure and pivoted to one,end thereofand provided with oppositely-extending and correspondingly-inclinedslots, and rivets on the opposite end of said structure adapted toengage in the said slots In 'testimonythat I claim the foregoing as myown I have hereto affixed my signature in the presence of two witnesses.
